Planetary Radio Extra: Shining a Million Watt Flashlight on an Asteroid

On This Episode

PlanRad’s celebration of Asteroid Day (June 30th) continues as we call UCLA grad student Adam Greenberg at the Arecibo Observatory in Puerto Rico. Under the direction of Professor Jean-Luc Margot, Adam is using the 305 meter/1,000 foot-wide dish to bounce radar pulses off a Near Earth Asteroid known as 2010 NY65. No other technique or tool for investigating asteroids offers the revelatory power of radar. And yet the Arecibo Observatory is in danger of losing its funding for this and all other research.
